Theory Grandmaster Yu Xiaogang

"What are you doing?" At that moment, a mild yet slightly hoarse shout rang out.

Ye Zhiqiu turned to look and saw a middle-aged man of average build, seemingly in his thirties or forties, standing beside them at some unknown point. He had short-cropped hair, wore a black robe, and stood with his hands behind his back, carrying an air of scholarly refinement.

Ye Zhiqiu narrowed his eyes at the middle-aged man. If he had guessed correctly, this was Grandmaster. Grandmaster was merely his title; his full name should be Yu Xiaogang, someone incredibly important to Tang San on the Douluo Continent.

He was also Tang San's lifelong teacher and played a crucial role in Tang San's early growth.

At that moment, Yu Xiaogang's brows were tightly furrowed. The gatekeeper seemed immersed in his own world and unable to free himself, completely ignoring his words.

For a gatekeeper to do something so disgraceful to the academy's reputation right at its entrance made Yu Xiaogang furious. If this went badly, the academy would bear this stain for the rest of its existence.

Ye Zhiqiu, meanwhile, secretly found it amusing. You think you can wake him up just by calling out to him? You're seriously underestimating the Sharingan.

Yu Xiaogang looked at the gatekeeper, who was still crazily wiggling his backside, and his face twitched. At last, he could no longer endure it. He rushed over and fiercely slapped him across the face.

"Slap!"

After the crisp sound, the gatekeeper flipped through the air before landing on the ground. He spat out several bloody teeth, and the left side of his face visibly swelled high.

The gatekeeper finally broke free of the Illusion Technique, but at the same time, Yu Xiaogang's blow had left him dazed. He lay on the ground blankly, clutching his face.

Yu Xiaogang picked up the two Spirit Hall certificates that had fallen from the gatekeeper's hand and examined them. Then his gaze shifted to Ye Zhiqiu and Tang San before finally settling on Old Jack.

"You must be here to enroll these two children, sir. To let you witness something like this as soon as you arrived is truly shameful. On behalf of the academy, I apologize to you." Yu Xiaogang gave Old Jack a slight bow.

A person who was at least a Spirit Master was apologizing to an ordinary man like himself, and Old Jack's vanity was immensely satisfied. Still, this absurd thing the gatekeeper had done seemed to be related to Little Qiu. Old Jack felt a little guilty, but he was an old hand at life and naturally would not bring it up himself.

Old Jack hurriedly waved his hands. "No need to apologize, no need. Then I'll have to trouble this teacher with these two children."

After seeing Yu Xiaogang nod, Old Jack gave Ye Zhiqiu and Tang San a few more reminders before setting off back to the village.

Only then did the gatekeeper recover somewhat. He stammered as he came forward, trying to explain, "Grandmaster, I..."

"You needn't come tomorrow," Yu Xiaogang snapped.

Then he led Ye Zhiqiu and Tang San into Nuoding Academy.

After the three had walked some distance, Tang San spoke up. "Teacher, we were also at fault just now."

Ye Zhiqiu's face darkened. You really are honest and dependable, Little Tang San. Just keep that sort of thing to yourself. Don't go saying I was the one who did it.

Yu Xiaogang smiled and waved his hand, assuming only that Tang San was being modest. "All right, it had nothing to do with you. Also, I'm not a teacher here. I'm just an idle man at the academy. They all call me Grandmaster, and you can call me that too."

"Not a teacher?" Tang San froze, then quickly said, "Then you must be someone very formidable."

"Oh? Why do you say that?" Yu Xiaogang asked curiously.

"Because only someone exceptionally skilled in a certain field deserves the title Grandmaster. And you can represent the academy, which means your status here must be very high," Tang San said seriously.

After hearing this, Yu Xiaogang burst into laughter. He raised a hand and rubbed Tang San's head. "Your Spirit Hall certificate says your name is Tang San, right? Little San, you are gifted and intelligent. Not only do you possess Innate Full Soul Power, you are also..."

At this point, a sharp gleam flashed through Yu Xiaogang's eyes. "You also possess Twin Martial Souls. It seems I must be stubborn for once as well. Are you willing to let me become your true teacher?"

As soon as the words fell, Tang San was stunned. How did Grandmaster know he had Twin Martial Souls? And did this mean he wanted to take him as a disciple? Should he agree?

Ye Zhiqiu scratched his backside and secretly sighed. Sure enough, even with me as this butterfly wing, the course of history won't change. The fated meeting between Grandmaster and Tang San was destined to happen.

Tang San did not speak, merely staring blankly at Yu Xiaogang. He neither agreed nor refused.

A trace of approval appeared in Grandmaster's eyes. "Are you wondering how I knew you possessed Twin Martial Souls?" As he spoke, Yu Xiaogang shook the two Spirit Hall certificates in his hand and continued, "It was because of these certificates. Others might not be able to spot the flaw in them, but if even I couldn't see it, then I would not deserve the title Grandmaster."

"I once investigated six hundred and seventy-one people whose Martial Soul was Blue Silver Grass. Among them, only sixteen possessed Soul Power, less than three percent, and not a single one had Soul Power above Rank 1."

"According to one of the Ten Core Competencies of Martial Soul that I have researched, Innate Soul Power is directly proportional to the strength of one's Martial Soul. Blue Silver Grass clearly does not meet that requirement."

"Of course, there are exceptions to everything, and that would be Martial Soul mutation, like Little Qiu." At this point, Grandmaster glanced at Ye Zhiqiu before continuing, "The certificate only states that it is a mutated Martial Soul related to the eyes. In my understanding, it is a type of Body Martial Soul. Whether it is truly mutated remains uncertain, but the fact that it could grant Little Qiu Innate Full Soul Power shows that this Martial Soul is extremely powerful and has great room for growth."

After using Ye Zhiqiu as an example, Yu Xiaogang returned to the subject. "But your Blue Silver Grass Martial Soul, Little San, clearly has not mutated, yet you still possess Innate Full Soul Power. Therefore, I dared to conclude that you must have another powerful Martial Soul."

After Yu Xiaogang finished speaking, he looked at Tang San confidently.

Tang San was utterly taken in by his words. Though there were parts he did not understand, he still felt that Grandmaster was incredibly impressive. Ye Zhiqiu secretly admired him as well. Yu Xiaogang's insight was indeed sharp; merely by looking at the certificate, he had basically figured out Ye Zhiqiu's Martial Soul. His Sharingan truly was not a mutated Martial Soul.

However, Yu Xiaogang's theory only applied to people of the Douluo Continent.

Ye Zhiqiu and Tang San were both freaks and did not fall within its scope.

Tang San's Twin Martial Souls came from his parents' inheritance, while his Innate Full Soul Power was the result of cultivating the Mysterious Heaven Skill.

Ye Zhiqiu's Martial Soul had been given by the system, and his Rank 20 Innate Full Soul Power had likewise been given by the system.

The two of them were both cheaters. Yu Xiaogang had merely stumbled upon the correct answer by chance.

He could fool Tang San, but he was still a little short of fooling Ye Zhiqiu.

Yet this did not negate Yu Xiaogang's accomplishments in Martial Soul research. When it came to researching Martial Souls, no one on the Douluo Continent could rival him. He was unquestionably the foremost authority on Martial Soul research on the Douluo Continent.
